Comments for Electron MC200 - Pulsing noise when switched on

Dear Kevin: My humble opinion is that the problem you describe should definitely be attended to by a qualified Organ/Keyboard technician. The little I have gleaned regarding the Electone MC 200 is that it was released by Yamaha in 1985, it looks pretty much like a three-tiered Spinet, and the (circuitry) innards are probably Solid State. Seek out a reliable technician with a proven track record in your area. What you decide to pay for the service depends on how much you "love" your MC 200. I own a much earlier (1976 DK 40 C) Electone and my few repair bills have been well worth the investment. Good luck, and thank you for participating in this Forum. You will always be welcome here with whatever questions/comments you may have.
